Abstract: An accelerator card can include a read-only memory configured to store a security identifier in a designated field therein and a satellite controller configured to read the security identifier in response to a reset event. The satellite controller is configured to select, based on the security identifier, a security mode from a plurality of security modes and implement the selected security mode in the accelerator card.

Abstract: Systems and method for synchronizing access to buffered data are disclosed. In such a method, video data is buffered in a frame buffer memory by a producer device. A write level indicator is provided to a synchronizer by the producer device. A read level indicator is provided to the synchronizer by a consumer device. The synchronizer compares the write level indicator with the read level indicator to determine a difference. The consumer device is informed by the synchronizer when the difference meets a sub-frame threshold. The consumer device reads the buffered data from the frame buffer memory on a sub-frame-by-sub-frame basis responsive to the informing.

Abstract: A system and method for replacing data in a cache utilizes cache block validity information, which contains information that indicates that data in a cache block is no longer needed for processing, to maintain least recently used information of cache blocks in a cache set of the cache, identifies the least recently used cache block of the cache set using the least recently used information of the cache blocks in the cache set, and replaces data in the least recently used cache block of the cache set with data from main memory.
